It is not recommended to feed pepperoni to cats. They have smaller and more delicate organs, such as the liver and kidneys, making them more vulnerable to pepperoni toxicity.
The high salt and fat content of pepperoni can cause upset stomach and diarrhea. In the long run, it can damage cat’s liver, stomach, kidneys, and bladder. Pepperoni often contains ingredients such as garlic, onion and other spices that are dangerous for cats.
Even if you know the exact pepperoni ingredients, it’s not advisable to feed your cat. Instead, stick to cat treats or other cat-friendly options like pumpkin or tuna in water.
